I have been contacted regarding a defaulted GC services student loan. For the past three years my tax were taken. I find the people at GC services to be very rude, unprofessional, uninformed, etc. The Dept of Ed said I have to deal with them in order to rehabilitate my loan. What are the steps I need to take and do I have to deal with GC services? I read so many bad things about them online? I borrowed $6,000 thirty-five years ago and it is now $21,000. Should I ask for a validation letter?
